Samsung has announced today the world’s first 64-megapixel sensor for smartphone cameras. The ISOCELL Bright GW1 expands Samsung’s 0.8μm image sensor lineup from existing 20Mp to ultra-high 64Mp resolutions.
There is more than one way for cleaning your camera sensor. However, it can easily happen that you make some mistakes when cleaning it, which can do your sensor harm in the long run. In this video, Michael The Maven talks about some of the most common mistakes people make. He also teaches you how to fix them, and proposes some effective methods for sensor cleaning.
Embarrassingly a few years ago I was very vocal about how disappointed I was about some of the Nikon lenses. I’ve been using Nikon cameras and lenses for decades and although I was very pleased with the image quality and colour rendition their cameras produced, I strongly considered jumping the Nikon ship in search of crisper, cleaner looking lenses. In fact I was so close to leaving Nikon a couple of years ago that I went through the process of hiring and testing other brands to see if other manufacturers could deliver what Nikon could not.
For the most part, phone camera resolutions seem to have been stuck between about 12-20MP for the last few years. But Sony plans to change that and make super high-resolution phones a thing, with the announcement of a new IMX586 stacked CMOS sensor. The new sensor packs a whopping 48MP and uses a new Quad Bayer array to maximise sensitivity and dynamic range.
A spec sheet has been leaked to the folks at Sony Alpha Rumors about a new Sony sensor. Of course, new sensors are released all the time, so what’s so special about this one? Well, it’s a 31MP resolution APS-C sensor with a global shutter that potentially offers 4K video at up to 108 frames per second though SLVS-EC – although much lower is more likely.
According to a recent report, Samsung Electronics is planning to increase its production capacity of image sensors. The company has set out to become number one business in image sensor market. And in this race, they reportedly plan to beat Sony and take the throne.
Well, it seems that Sony isn’t the only one with a global shutter CMOS announcement of late. According to a press release, Panasonic has also just announced a new global shutter CMOS sensor. This one, though, is capable of shooting up to 60 frames per second at 8K (36MP) resolution. Unlike Sony, which utilises a rear illuminated design with parallel DA converter, Panasonic’s uses an organic photoconductive film (OPF) to allow simultaneous readout of all the pixels on each frame.
Have you ever wondered why camera lenses produce a circular image circle (in general) but sensors are rectangular? Of course the answer is mostly historical – the format of a 35mm photo is in 3:2 aspect ratio, a ratio that people have long known to work well due to human binocular vision.
But lenses, in general, are circular. they produce an image circle, a circle that, in general, allows the 35mm sensor to just fit inside it. You don’t want your image circle much bigger than this (except for tilt-shift lenses) because that makes your lenses heavier and more expensive.
Well, this is a surprise and not an unwelcome one. Few people seem to realise that as well as being a leading 3rd party lens manufacturer, Sigma also make cameras. I have actually had the pleasure of playing with a Sigma sd Quattro for the past few weeks, and it’s pretty impressive if a little on the slow side. The Foveon sensor does produce some truly beautiful results.
That lack of speed, though, has put off many potential Sigma camera owners. Now, a new patent has been filed showing that Sigma looks to be doing something about it. The patent seems to aim more toward the video side of things but no doubt it will speed up its stills capturing capabilities, too. Perhaps this is why Sigma semed a little evasive about camera questions recently at PPE.
